IPC: F28D1/053
Filed: 1989-07-26
Abstract: PURPOSE:To improve the accommodating property of a heat exchanger into an outdoor unit and increase the front area of the heat exchanger to contrive the reduction of noise as well as the improvement of COP by a method wherein at least one place of bent part is provided in an upper header tube and a lower header tube so as to be opposed and flat heat transfer tubes are connected to the headers excluding the bent parts while fines are arranged alternately and are brazed to the flat heat transfer tubes. CONSTITUTION:Fins 2 and flat heat transfer tubes 1 are arranged alternately and the fins 2 are brazed to the flat heat transfer tubes 1. The upper ends of the flat heat transfer tubes 1 are connected to an upper header tube 3A excluding a bent part 5A while the lower ends of the flat heat transfer tubes 1 are connected to a lower header tube 3B excluding the bent part 5B to constitute a heat exchanger 4. A ventilating fan 6 is positioned in front of the heat exchanger 4 and heat exchange is effected by forced convection. An outdoor unit 7 accommodates the heat exchanger 4 and the ventilating fan 6. The heat exchanger 4 is provided with the bent parts 5A, 5B and the front area thereof is increased. According to this method, the rotating number of the ventilating fan 6 may be reduced and the reduction of noise may be contrived. On the other hand, the heat radiating capacity of the heat exchanger 4 is increased and, therefore, the condensing temperature of the heat exchanger 4 may be set at a low temperature and the COP of the outdoor unit 7 may be improved.

Title: Semiconductor device and manufacture thereof
Inventor: KOBAYASHI HITOSHI
IPC: H01L27/08
Filed: 1989-07-27
Abstract: PURPOSE:To facilitate the control of a film thickness of a silicon layer by sandwiching a resistor layer with an upper silicon layer and a lower silicon layer and forming an oxide silicon layer on said upper silicon layer. CONSTITUTION:A lower insulating layer 1 is formed on a silicon semiconductor substrate. On this lower insulating layer 1, a lower silicon layer 2, a resistor layer 3, an upper silicon layer 4, and a silicon oxide layer 5 are formed in order without breaking a vacuum state. As the upper silicon layer 4 is not exposed to an atmosphere, it is not oxidized. Accordingly, a film thickness of the upper silicon layer 4 can be made thin. Subsequently, the lower silicon layer 2, the resistor layer 3, the upper silicon layer 4 and the silicon oxide layer 5 are patterned into a predetermined shape. Next, a protective insulating layer 6 is formed so as to cover the silicon oxide layer 5. Then, in order to form a contact hole, the protective insulating layer 6 and the silicon oxide layer 5 are etched. The surface of the upper silicon layer exposed by the etching becomes a contact part 7. Next, a metallic layer 8 as an electrode is formed so as to be in contact with the contact part 7, thereby obtaining a semiconductor device.

Title: Manufacture of semiconductor device
Inventor: ENDO TOSHIO
IPC: H01L23/522
Filed: 1988-08-06
Abstract: PURPOSE:To prevent device yield from being lowered by eliminating conductive foreign matter on a second conductive wiring by forming a third insulating film pattern on a semiconductor substrate through a first conductive wiring pattern, and further forming a second conductive wiring pattern on the upper part of the third insulating film pattern. CONSTITUTION:There are formed on a semiconductor substrate 1 a first conductive wiring 2 pattern, a third insulating film 3 pattern, a second conductive wiring 5 pattern, and a passivation film. The insulating film 3 pattern 4 is constructed so as not to produce its etched substrate upon etching because of the existence of the wiring 2 pattern. Accordingly, the insulating film 3 pattern has the same shape as that of the insulating film 3 in another wafer and prevents a photoresist from being partly left behind upon a photolithography process. Thus, conductive foreign matter on the wiring 5 is eliminated to prevent device yield from being lowered.
